Embodiment 1

[0026] figure 1 It is a flow chart of the method for inter-device intranet communication provided by Embodiment 1 of the present invention, specifically including steps S101 to S103, which are described in detail as follows:

[0027] S101. The server joins a preset multicast group, and monitors a preset multicast address and a preset multicast port.

[0028] Multicast (Multicast) is a communication mode, which refers to the realization of point-to-multipoint network connection between the sender and each receiver. If a sender transmits the same data to multiple receivers at the same time, it only needs to copy the same data packet.

[0029] Specifically, the server joins a preset multicast group, and the multicast group provides a preset multicast address and a preset multicast port number, and the server joining the multicast group will Monitor the multicast address and multicast port.

[0030] Further, the preset multicast address can be selected within the range of 239.0...

Abstract

The present invention relates to the field of communication technology, and provides a method and system for inter-device intranet communication, aiming to solve the problem that in the prior art, the process of realizing inter-device intranet communication through server transfer depends on the connectivity of the entire link and requires resource costs support questions. The method includes: the server joins a preset multicast group, monitors the preset multicast address and the preset multicast port; The IP address of the client; the client and the server transmit data packets through HTTP according to the acquired IP address of the other party. The present invention discovers all devices in the intranet through multicasting, and obtains each other's IP addresses, so that data transmission between devices can be performed through HTTP, so that intranet communication between devices can be realized without relying on server transfer, ensuring The arrival rate of data transmission avoids the resource cost investment caused by the use of transit servers.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and system for inter-device intranet communication. Background technique [0002] With the rapid development of the Internet of Things, more and more smart hardware is emerging. These smart hardware can be used with terminals such as mobile phones or tablets to conveniently realize the control and monitoring of various smart devices. In the early days, most smart hardware used Bluetooth as a data transmission channel, but the Bluetooth transmission method is only suitable for short-distance communication and has limitations in distance. Now, more and more smart hardware starts to use WIFI (Wireless Fidelity, Wireless Fidelity) for communication, which can quickly connect to the Internet based on the existing home or public network, and realize short-distance or long-distance communication. [0003] At present, WIFI-based intelligent hardware communication ...
